As a W3C Recommendation, CSS1 was released on December 17, 1996. On January 11, 1999, this recommendation was revised.

As a W3C Recommendation, CSS2 was released on January 11, 1999. CSS2 added support for media (printers and aural devices) and downloadable fonts.

CSS3 plans to divide CSS into smaller modules.

Starting with CSS3, modules will be defined separately. For example, CSS4 selectors can be defined in the CSS3 module.
